Hello everyone I need to acquire some information. About 6 months ago I purchased a healthy, baby Marginated tortoise. Sadly he died last night and now I am trying to figure out how he died and how I can avoid it with future tortoises. For a week and half before he died he got very sluggish and slept nearly non-stop. I would give him fresh food everyday with calcium powder sprinkled on it, but he wouldn't eat anything I gave him for the week and a half before he died. Since this was near the start of fall I suspected that he may have been in some sort of hibernating slumber or something, but the temperature inside of his tank stayed roughly around 75-85 degrees Fahrenheit during the day and around 65-75 degrees Fahrenheit at night, so I was not fully sold on the idea that he was hibernating. I would bath him regularly two times a week for 10 minutes in lukewarm water. I did have calcium sand for his substrate and some of the marginated tortoise care websites suggest that that kind of substrate can be potentially harmful to them, but others sites I went to suggested calcium sand and other types of sand were better to have for them over any other kind substrate, so I am not fully sure if he died from the sand. I know he would, on occasion, eat the sand, so I am not sure if it caused some kind of intestinal blockage or something. Also I kept his lights on timer that would turn off his lights at 9 pm and turn back on at 8 am. SO, if anyone has any relative information about the symptoms he had before he died or any critiques about my care for him that may have been the cause of his death please let me know. I really would like to give raising a marginated tortoise another try, so if anyone possess any information that might allow me to avoid the death of another tortoise in the future, please let me know.
